Peter Rimshnick Hi Professor - big fan of your research.. I was wondering what Anton Z. thinks of the prospects of your experiments? Best of luck!

The string theorists who wrote the preprint (not a published paper) about "fate" preventing the operation of the LHC were being facetious. I note that the RHIC facility that I use had a somewhat similar disaster when it was starting up, but it has been in operation now for almost a decade without destroying the universe (yet). [note: the "yet" is me being facetious.]

On various online forums I had been pointing out the parallels between the "fate" paper and EINSTEINS'S BRIDGE.

Reminds me of a causality-preserving mechanism suggested, I believe, by Larry Niven. If you build a time machine and go back and try to change the past, the universe will prevent you from doing so by the simplest means possible, which is ... you guessed it ... no time machines will be built!

Mark Hughes By the way, I'm an Engineer in the Oil Industry with only an interest in theoretical physics, but have always had a dream of setting up my own funded physics lab in the basement to run my own entanglement experiments and such.... is setting up the required equipment a fairly affordable venture or is the right equipment... for these experiments something that may cost something in the 6 figures!?

Dear Mark,



You are probably correct about the 6 figures. The new specialized equipment I'm using cost around $30k. That does not include the much larger cost of the already established laser physics laboratory I'm using, which was previously occupied by Nobel Laureate Hans Dehmelt. There is an article in American Journal of Physic, vol. 72 #2... See More. pp.127-140, February 2005, by E. J. Galvez, et al. describing how a group in the Colgate U. Physics Dept. set up a quantum optics lab as part of their laboratory courses for advanced undergraduates. They reported a total cost of $25k with about $9k for specialized items. However, I could not do my experiment with their setup.

Mark Hughes Hi Professor Cramer, love your work. Good luck with the retrocasuality experiment, hope that signal to noise issue can be fixed and isn't a brick wall :). Kudos to you though for pushing the envelope and keeping science interesting and exciting for the masses.

PS if you do get it up and running in the future, could you ...message me next weeks lotto results? Cheers ;)

A speed distance experiment? Whatcha proving? Using both red and green lasers? I'm curious...

The experiment is to see if quantum non-locality can be used for communication.

The Violet laser is for the experiment. The green is a laser pointer used to test alignment of the equiptement to save the laser for the experiment.

That time-honored standby of science fiction — traveling back in time — has come back into fashion in Hollywood, and physicists are trying to find out how much truth there is in the concept.

Thanks John--so your ideas could lead to instantaneous communications gadgets then! By the way, the mission is to all the planets in the Solar System, not to the star Anataries---the ship is named Antaries. For a good summary, with good shots and videos, see--

More people should watch this show--it has potential I think...

Hi John,

You may want to take a look at the most recent episode of Defying Gravity-

Defying Gravity:Season 1 Episode 9: Eve Ate the Apple... See More
http://www.ch131.com/defyinggravity109.htm

This episode can bring new viewers up to date, and also reveals the true nature of the mission--with a physics slant you may find interesting.

By the way, you seem to have disappeard off of my friends list... :(

John G. Cramer The Quantum Liar Experiment in Cramer’s Transactional Interpretation
R. E. Kastner
University of Maryland, College Park
Version of Aug. 31, 2009
ABSTRACT. Cramer’s Transactional Interpretation (TI) is applied to the
“Quantum Liar Experiment” (QLE). It is shown how some apparently
paradoxical features can be explained natural...ly, albeit nonlocally (since TI is an
explicitly nonlocal interpretation).

John G. Cramer Twistor was my first novel. Writing it resulted in a nomination for the Compton Crook Award (Best 1st Novel, 1990) and in two nominations (1990 and 1991) for the John W. Campbell Award (Best New Writer). It was also on the semi-final ballot for the 1991 Nebula Awards.
